Thank you very much for purchasing the products of Trevor. Recently, we found that some of our products in circulation on the market, in which part of the contents on the product labels are smeared and other means of deliberately hiding label information. Such products that are deliberately destroyed and hidden label information are not our quality assurance objects. Please understand! Recently, we found that counterfeits are in circulation. Here are some recent examples. Some companies have no business with our company, but forge our company's power of attorney, claiming to be our regular agent to sell our counterfeits. Some companies have no business with our company. They claim to be our regular agent on the e-commerce website and sell our imitations. Some customers bought the imitations which they called "treixiang products" from the company which has no business relationship with our company, and the quality accident occurred after the installation of the customer company. Imitations are not only the quality assurance object of our company, but also may lose the product quality and brand image of customers. Therefore, it is suggested that in order to avoid purchasing imitations by mistake, please purchase the products from the sales company, sales branch and regular agents of tranex. In order to avoid purchasing fake products with poor quality by mistake, please purchase the products from the sales company, sales branch and regular agents of tranex. Products purchased from informal distribution channels do not belong to our quality assurance object, please understand! For information about suspicious sales companies, please contact our sales department. Products that are intentionally damaged and hidden label information are not our quality assurance objects. Please understand!
